Is this safe? |feed_as_dict| looks to be simultaneously owned by |raw_value| and
|resource_list_value_|.

[satorux1, 2013/01/09 00:50:49]

Should be safe. Remove() above transfers the ownership to |feed|. Added a
comment.

[kinaba, 2013/01/09 01:36:23]

Ah, sorry, you're right.

We should better do PostTask here as well as in GetResourceList. Same for all
other "callback.Run"s.

Good catch! Done.
